진열대에서 봄 부트 템플릿 : spring-boot-starter-log4j2, spring-boot-starter-web 및 spring-boot-starter-actuator.왜 스프링 로거가 org.springframework에서 상속되지 않는가?
나는 log4j2가 WARN 이상인 경우 Spring 관련 메시지 만 기록하려고합니다. 나머지는 DEBUG 이상을 기록하고 싶습니다.
Log4j2의 설정은 다음과 같습니다
<Configuration status="DEBUG">
<Appenders>
<Console name="STDERR" target="SYSTEM_ERR">
<PatternLayout>
<pattern>%highlight{[%level]} %logger %message %throwable%n</pattern>
</PatternLayout>
</Console>
</Appenders>
<Loggers>
<Logger name="org.springframework" level="warn" />
<Root level="debug">
<AppenderRef ref="STDERR"/>
</Root>
</Loggers>
</Configuration>
를 작동하지 않는 몇 가지 이유 : org.springframework.boot.actuate.endpoint.mvc.EndpointHandlerMapping이 STDERR에 추가합니다. 따라서 org.springframework.boot.web.servlet.FilterRegistrationBean, org.springframework.boot.logging.ClasspathLoggingApplicationListener 및 기타 여러 가지가 있습니다.
org.springframework.boot.actuate.endpoint.mvc, org.springframework.boot.web.servlet, org.springframework.boot.logging 등의 레벨을 수동으로 설정할 수 있습니다. 왜 그런지는 알 수 없습니다.
로거 설정은 org.springframework 로거 설정에 바인드되어 있고 레벨이 WARN입니다.
